Abstract
A system for generating direct manipulation office systems is described.
In these systems, the user directly manipulates graphical representations
of office entities instead of dealing with these entities abstractly
through a command language or menu system. These systems employ a
new semantic data model to describe office entities. New techniques
based on attribute grammars and incremental attribute evaluation
are used to implement this data model in an efficient manner. In
addition, the system provides a means of generating sophisticated
graphics-based user interfaces that are integrated with the underlying
semantic model. Finally, the generated systems contain a general
user reversal and recovery (or undo) mechanism that allows them to
be much more tolerant of human errors.
